Possible Causes for the Roller Drum Not Turning
There are several reasons why a roller drum might fail to turn, and understanding these can help pinpoint the issue. Below are the most common causes:
- Hydraulic System Failure
- Many roller drums are powered by hydraulic systems. If the hydraulic pressure drops or there is a problem with the hydraulic motor, the roller drum may fail to turn. Leaks, clogged filters, or low fluid levels could be responsible for the hydraulic failure.

- Drive Motor Problems
- The drive motor that powers the roller drum may malfunction, which can cause the drum to stop turning. This could be due to electrical issues, mechanical failure, or worn-out motor components.
- The drive motor that powers the roller drum may malfunction, which can cause the drum to stop turning. This could be due to electrical issues, mechanical failure, or worn-out motor components.
- Electrical Faults
- If the machine’s motor is electrically controlled, a fault in the wiring or a blown fuse could prevent the motor from engaging, leading to the drum not turning. Issues such as faulty sensors, relays, or control systems can also cause this problem.
